Repeating firearm of the linear type with assisted ejection

ABSTRACT

Said firearm is characterized in that the locking means are made up of the hammer (5), which cooperates with the movable assembly, to lock the movable assembly at the rear position of movement.

The invention relates to the technical field of firearms.

The invention more particularly relates to a manual repeating firearm of any caliber, in particular of the linear type, with assisted ejection.

This type of firearm comprises, in a known manner, means capable of recovering energy resulting from pressure exerted when firing an ammunition to move a movable assembly against a return spring, said assembly including a stopper, a latch and a striker cooperating with a hammer controlled by a trigger.

More specifically, the invention relates to an improvement regarding document FR 3,019,887, also held by the Applicant hereof.

According to the teaching of this document, the firearm, of the type defined above, has:

-   -   locking means for locking the movable assembly in a compressed         position of the return spring at a rear position of movement of         the movable assembly, after each shot,     -   a manually actuatable unlocking assembly capable of acting on         the locking means to release the movable assembly to allow the         assisted return of said movable assembly to perform an         ammunition reloading.

In light of the locking at a rear position of movement of the movable assembly, the user must, after each shot, intervene manually before reloading the ammunition, with the assisted return.

Such a manual intervention is mandatory, and therefore allows the firearm to remain in the category of so-called repeating firearms, of the semi-automatic type.

Furthermore, the unlocking assembly cooperates, when it is actuated, with a part able to neutralize the striker of the firearm, by disengaging the trigger.

From this state of the art made up of the teaching of document FR 3,019,887, there was a desire to simplify the locking means, with the aim of discouraging shunting such means.

According to the invention, in order to resolve such a problem, the locking means are made up of the hammer, which cooperates with the movable assembly, to lock the movable assembly at the rear position of movement.

It emerges from these features that one acts on a master part, which is the hammer.

In order to resolve the posed problem of avoiding shunting of the locking at a rear position of movement of the movable assembly, the unlocking assembly cooperates, when it is actuated manually, with two parts able to neutralize the striker of the firearm, by making the hammer inoperative.

In one embodiment, the two parts are made up of an unlocking finger and an unlocking notch, the unlocking notch having a beak cooperating with a boss of the hammer to cause it to drop and unlock the movable assembly, when the unlocking assembly is actuated manually.

According to other features, the unlocking assembly is secured to the unlocking finger, using a pivot axis of said unlocking assembly.

The pivot axis has a polygonal male step cooperating with a female cavity having a complementary shape formed in a thickness of the unlocking finger.

The unlocking assembly is a lever accessible from outside the firearm.

The invention is described below in more detail using the figures of the appended drawings, in which:

FIG. 1 is a perspective view of the trigger guard, in particular showing the hammer subject to the unlocking assembly,

FIG. 2 is a front view, corresponding to FIG. 1,

FIG. 3 is a side view of FIG. 2,

FIG. 4 is a top view of FIG. 1,

FIG. 5 is a longitudinal sectional view, considered along line AA of FIG. 3,

FIG. 6 is a sectional view, considered along line BB of FIG. 4.

As emerges from the teaching of document FR 3,019,887, the receiver of the firearm receives a movable assembly, not shown, essentially made up of a stopper, a latch and a striker, which is struck under the effect of the tilting of a hammer (5), controlled by a trigger (6).

The operation of this type of firearm is not described, since it is perfectly well known for one skilled in the art.

The firearm has an unlocking assembly (12), able to be actuated manually, and capable of acting directly on the hammer (5), to release the movable assembly and to allow the assisted return of said assembly for reloading. The unlocking assembly is made up of a maneuvering lever (12), accessible from outside the firearm.

More specifically, the unlocking lever (12) is subject to the hammer (5), which therefore makes up the locking means by cooperating with two parts (15) and (15 a), which are capable of neutralizing the striker of the firearm, therefore making said hammer (5) inoperative.

As shown more particularly in FIG. 5, these two parts are made up of an unlocking finger (15), and an unlocking notch (15 a).

The unlocking lever (12) is secured to the unlocking finger (15), using a pivot axis (13) of said lever (12), said axis being engaged transversely, FIG. 6.

More particularly, this axis (13) has a polygonal male step, for example in the form of a square, cooperating with a female cavity having a complementary shape, formed in a thickness of the unlocking finger (15).

Thus, when one acts on the unlocking lever (12), the unlocking finger (15), which cooperates by bearing with the unlocking notch (15 a), acts on said notch, which has a beak cooperating with a boss of the hammer, to cause said hammer to drop.

As a result of these features, the locking at a rear position of movement of the movable part is done directly by the hammer, which constitutes a master part of the firearm.

The advantages emerge clearly from the description.
